In utero head traumas are extremely rare and are usually caused by penetrating injuries in the thoracic or abdominal wall that affect the uterine cavity. Transvaginal fetal head injuries have been reported in exceptional cases. This is a case-report of a fetus affected by penetrating head trauma with skull fracture and intra-ventricular hemorrhage after his mother's self-insertion of a blunt object, violently through the vagina. Trauma disrupted the integrity of intrauterine membranes and precipitated preterm labor. After birth, there was a debridement of the scalp and surgical management of the fracture was performed; nevertheless, the patient died four weeks later, due to neonatal sepsis. Management of these wounds must not only be focused on repairing the primary wound, but on preventing the infectious complications.
